What? Fifth Gear tests all the cars that Top Gear tests. Most recently they tested the Pagani Zonda F and the Koeniggsegg CCR. They even got to "test" a BMW-Williams F1 car.

I saw the Zonda episode, but not the CCR... Maybe I'm just missing them, even though I DVR every episode.
The last one I watched was their favorite sports car episode, Boxster won that one. Loved watching Tiff beat the hell out of the car.
